Answer 1

Something like:

var matches = states.Where(state => state.Contains(searchText));

That’s fine if the case matches as well, but it doesn’t work so well for case-insensitive matches. For that, you might want something like:

var matches = states.Where(state => 
      state.IndexOf(searchText, StringComparison.OrdinalIgnoreCase) != -1);

Choose the exact string comparison you want appropriately – you might want to use the current culture, for example.
